I picked up, out of the clearance bin, a "DU/Briley" labeled choke tube. It is marked "INVP GOOSE". It's an extended tube with camo on the end.

I'm sure the "INVP" = Invector Plus. My question is, to what choke does "goose" equate?

For $5.00 each, I know couldn't/can't go wrong.

Thanks in advance!

I would guess it is an IM .025" constriction. See the link to Briley's site with that choke.

Under Hunting chokes hit select and it will show the chokes and names.

Good luck.

Browning has had 2 different types of chokes over the years. Invector and Invector Plus.
My guess is you have the standard Invector unless there is the "+" sign on there. The plus chokes are clearly longer than the standard chokes. They are NOT interchangable.

I would agree that the restriction you have is more than likely Impoved Modified.

Thanks for the replies!
I'm pretty sure it's Invector Plus.
IM sounds good to me!
